PostgreSQL User

A PostgreSQL User is a login user inside a specific PostgreSQL Cluster's own catalog. It is the real access path for that cluster — the cluster resource itself has no user-facing credential, so create at least one User to actually connect.

Key concepts

• Belongs to one cluster forever — spec.postgreSqlId is required and immutable; a user cannot move between clusters

• Write-only password — spec.password is never echoed back by the API, same as every other credential field on this platform. Omit it on a modify to keep the current password

• No default user — creating a cluster does not create a user automatically; this mirrors how a fresh Kubernetes cluster has no default KubernetesUser either

Parameters
UI Name API / kc name Terraform name Optional Format Default Is read only Description
PostgreSql cluster spec.postgreSqlId spec.postgre_sql_id No ULID — references a PostgreSql cluster — No Immutable after creation
Password spec.password spec.password Yes string (sensitive, write-only) — No Never returned in status. Required when login is true; not required (and has no effect) when login is false
Login spec.login spec.login No boolean — No A login user with no password can never actually connect
Connection limit spec.connectionLimit spec.connection_limit Yes integer a share of the cluster's connection budget, at most 50 No Maximum concurrent connections for this user. Left unset, the user gets a share of what the cluster's nodes can actually serve, divided among the users that did not ask for a specific number. When set, it must cover every database this user can reach — the granted ones plus the maintenance database — because the pooler keeps a separate connection pool per database and divides the limit across them
Granted database ids spec.grantedDatabaseIds spec.granted_database_ids Yes list of ULIDs — references PostgreSqlDatabase resources [] (no databases granted) No The PostgreSql Database resources this user is granted access to
